It looks legit to me, but also, since it's on an electric keyboard, the music could already be playing and the keys lighting up give the illusion that the chicken is actually playing the piano.
There are some amazingly beautiful chickens, including some that are just supposed to be house pets. I met a breeder a few weeks ago who was telling me all about her chickens. And I'm semi- obsessed with Silkie chickens.Don't think I have ever seen a chicken that was so pretty.
